Now we can tell or explain partly how the most solar systems were created and not only that we know also how a planet affects us, with the classical physics and how physics on large scales work, for example travelling with light speed or near lightspeed and so on. But now we will focus on the smaller scales. That is like the hypest part in physics of them all because nothing seems to be like we used to. I mean an electron is able to travel as a wave trough space. Did you ever travelled in all spatial dimension at once ? Its not intuitive for me ^^ans should be for you aswell either you sit in a silicon plate and do computing stuff. Im talking about quantum physics. Its the hardest part of Physics as far as i know. And there are really crazy phenomena since we got to deal with formulas. Wave particle duality ok, double slit experiment explains its pretty well with light and its wave properties, but the light wave is quantized by its energy frequency, that means it has like a particle porperty. Super position is like being at severall states at once, being at 2 positions at once until you make a measurement. Its kind of the freakiest physics ive ever seen. Lets start with atomic theory and how atoms build firstly it were lile a whole then they discovered protons and neutrons are in the nuclei, then that the electrons have orbits around the nucleus with different energy level to that electrons are actually in a kind of cloud around the nucleus since theyre also waves like debroglie proposed, they have no firm state there are different possibilities for them to be in different regions around the nuclei. Thats crazy somehow. But you know these quantum properties get broken down when you let them interact atleast with a photon, because these light thingies are also force carriers for the electromagnetic fields in which all atoms sit. Einstein received his nobelprize for the photoeffect, which explains why different wavelengths can kick out an electron from a steel plate or not, either they got enough energy to kick the electron out of its orbit or not. Then there is nuclear physics, this field describes for example how nuclear powerplants are able to split heavy atoms or the fusion light elements into heavier ones like the sun does, I already explained that so. Particle physics is trying to research for new fundamental particles like the higgsboson got discovered by the Large hadron collider. And the best description of our universe is the quantum field theory where people lile feynmann worked with or his diagramm show how these particles interact with each other in all possible ways, which looks crazy or is able to look crazy but since its physics its just looking at formulas and make yourself looking crazy :D. But dont mind people of the wonderful internet, without the idea of the LHC back in the 1960 and 1970 there wouldnt be internet like we got it today. It may have been some sort of other source but its the physicists which improves the world with its ideas. But there is a problem there is something missing really big. Nobody cant explain what is going on in a blackhole or what darkmatter is or how dark energy works, that leads the philophical physicists into a great chasm of ignorance how the universe really works on all levels.
Man we learned allot about how the physics changed our world and view atleast mine and im happy that im able to share it with someone.
